GitLab has remediated an issue in GitLab EE affecting all versions from 16.10 before 18.9.7, 18.10 before 18.10.6, and 18.11 before 18.11.3 that when instance-level approval rule editing prevention was enabled, could have allowed an authenticated user with Maintainer permissions to modify or delete project approval rules due to missing authorization checks.
